Half the fun in this outlandishly funny sitcom is that Penny is so spacey that she doesn't appear to recognize what hard-core nerds Leonard and Sheldon really are--even the presence in their bathroom of Luke Skywalker No-More-Tears Shampoo doesn't tip her off.

This is a comedy that does what it's supposed to do, which is to make you smile and giggle at the appropriate points. Be that as it may, the pilot never ascends beyond the level of being cute and nice.

Brian Lowry

That said, there are some qualms surrounding how long the producers can mine the Leonard-Penny aspect of the show, a shallow vein if there ever was one. More promising is the interaction among the key duo and their Mensa-worthy friends.

It's just the same joke endlessly repeated--the everyday translated into geek-speak, and the obscure and difficult treated as if it were common knowledge.... These are perilous times for sitcoms, and Lorre & Co. may want to think up another.

Aaron Barnhart

I didn't get much of a sense where this show was going from the pilot, though there was nothing to hate about Big Bang Theory, and the writing’s every bit as sharp as "Two and a Half Men" and "Dharma & Greg," comedies overseen by Big Bang producer Chuck Lorre.

Alessandra Stanley

"Chuck" has interests similar to those of the heroes of Big Bang, including a lack of interest in chasing women, but his comedy is more inventive--the better bet in a new era in which the nerd no longer loses, but the best nerd show wins.

David Hinckley

Robert Abele

While it's got that professional Burrows sheen of unerrant joke delivery--especially from the talented Galecki, who can do this in his sleep--you have to assume the pile of scripts on his desk in this hurting age for the three-camera studio-audience format isn’t what it once was.

Henry Goldblatt

Matthew Gilbert

The show might even have been engaging, if the one-liners came less frequently and the characters had a little more dimension. As it is, Sheldon and Leonard are merely laughable, if sweet, and they are even less fleshed out than the characters on "Two and a Half Men."

Todd R. Ramlow

Other shows do complicate and elaborate the geek mystique ("CSI" and "Bones" come to mind), but all we’re likely to get from The Big Bang Theory are missed communications, fumbled opportunities, and general yuckety-yucks.

Mike Duffy

This is by far the least charming--the lame, leering sitcom tales of two brainiac losers (Johnny Galecki, above, and Jim Parsons) goofily smitten by the babelicious girl next door (Kaley Cuoco). It's about as witty as a pocket protector.
